Coin making has been a common practice since about six or seven thousand years BC. Coins are used as currency and give a monetary value to a piece of metal. It also facilitated trade so farmers could trade in their wares for coin which they could in turn exchange at marketplaces for tools or furniture or even clothing. Currency literally changed the world in terms of trading and employment.
Coinage is also issued to commemorate special events, such as coronations, the birth of royal family members or sports tournaments such as the World Cup and special coins are also minted to commemorate special anniversaries.
A notable currency is the euro which is used by some countries in the European Union. This is a shared currency and while the notes are standard issue across the Eurozone, each member state of the monetary union designed the obverse side of each denomination of coin to reflect the identity of each member state.
